The atomization component generally is installedon one end of the e-liquid storage cavity, including a porous bodyconfigured for absorbing and transmitting the e-liquid and a heatingelement, arranged on the porous body, configured for atomizing thee-liquid absorbed and transmitted by the porous body.

During the process of smoking of electronic cigarette, as the e-liquidin the e-liquid storage cavity is continuously consumed on the porousbody, a situation of negative pressure will occur in the closed liquidstorage cavity; in order to offset the negative pressure to reach an airpressure balance, the external atmospheric pressure will continuouslysupplement air into the liquid storage cavity through the porous body,which is the phenomenon of liquid bubbling we have ever seen. Since theliquid guide for atomization and the air pressure compensation both actat one same position of the porous body, in addition, the direction ofliquid guide is downward while the direction of air pressurecompensation is upward, namely, the liquid and the air flow in oppositedirections, the air pressure compensation will influence the supply ofliquid guide and leads to the occurrence of burnt smell.

DETAILED DESCRIPTION

For a better understanding, the present disclosure is described below infurther detail in conjunction with accompanying drawings and specificembodiments.

Embodiment 1

With reference to FIG. 1 to FIG. 4 , the present disclosure provides anatomization assembly, including an e-liquid reservoir 1, a porous body2, a heating element 3, an electrode 4 and a magnetic element 5, whereinthe e-liquid reservoir 1 includes an aerosol channel a, an e-liquidstorage cavity b used for storing an e-liquid, and an air inlet channelcommunicated with outside of the atomization assembly. The e-liquidreservoir 1 includes an e-liquid storage sleeve 11, a sealing seat 12, afixing seat 13 and a blocking seat 14; the e-liquid storage sleeve 11includes a sleeve body portion 111 and a tube body portion 112, the tubebody portion 112 is accommodated in the sleeve body portion 111, aninner space of the tube body portion 112 forms the aerosol channel a,the e-liquid storage cavity b is formed between the tube body portion112 and the sleeve body portion 111, and the e-liquid storage cavity bis arranged surrounding the aerosol channel a.

The sealing seat 12 is accommodated in the e-liquid storage sleeve 11and is sleeved on the porous body 2, and a peripheral surface of thesealing seat 12 presses against the e-liquid storage sleeve 11elastically to seal the cavity opening of the e-liquid storage cavity b.The sealing seat 12 includes a first perforation 121, a secondperforation 122 and a third perforation 123; both of the firstperforation 121 and the third perforation 123 are communicated with thee-liquid storage cavity b. The second perforation 122 is located betweenthe first perforation 121 and the third perforation 123 and is spacedfrom the first perforation 121 and the third perforation 123. A firstend of the tube body portion 112 is connected to the sleeve body portion111, and a second end of the tube body portion 112 is inserted into thesecond perforation 122.

The fixing seat 13 is installed on an end part of the e-liquid storagesleeve 11 and located on an end surface of the e-liquid storage sleeve11. The fixing seat 13 and the e-liquid storage sleeve 11 are ininterference fit or buckled connection, etc., and no concrete limitationis made here. In the present embodiment, the fixing seat 13 and thee-liquid storage sleeve 11 are in interference fit, a peripheral surfaceof the fixing seat 13 is further sleeved with a sealing ring 6, and thesealing ring 6 presses against an inner wall surface of the e-liquidstorage sleeve 11 elastically. The fixing seat 13 presses against thesealing seat 12, the fixing seat 13 includes the first e-liquid holdingtank 131, and the first e-liquid holding tank 131 faces the porous body2, thereby being able to collect the e-liquid leaking from the porousbody 2 or a condensed e-liquid formed on the aerosol channel a.

The fixing seat 13 includes an air inlet 132, the air inlet 132 passesthrough a bottom wall of the first e-liquid holding tank 131, and an airexit of the air inlet 132 is higher than the bottom wall of the firste-liquid holding tank 131, thereby being able to prevent the e-liquidinside the first e-liquid holding tank 131 flowing out from the airinlet 132 and better avoiding leakage of e-liquid. The blocking seat 14is located between the porous body 2 and the fixing seat 13 and pressesagainst the porous body 2, so that the porous body 2 is more firmlyfixed. The blocking seat 14 includes an air groove 141, a bottom wall ofthe air groove 141 includes an air through-hole 142, and the airthrough-hole 142 is communicated with the first e-liquid holding tank131 and the air groove 141. In the present embodiment, the blocking seat14 is made of a silicone material, which can better seal the porous body2. The air inlet 132 serves as the air inlet channel. It isunderstandable that the structure of the e-liquid reservoir 1 may bearranged as needed, as long as it can be configured for storing ane-liquid, and no concrete limitation is made for the structure here.

The porous body 2 is used for adsorbing the e-liquid in the e-liquidstorage cavity b, the porous body 2 includes an e-liquid guide wall 21and an air inlet wall 22, and the e-liquid guide wall 21 is configuredfor guiding the e-liquid in the e-liquid storage cavity b to the heatingelement 3 to atomize. The air in the air inlet channel can flow into thee-liquid storage cavity b through the air inlet wall 22, which means theporous body 2 does not require an extra air hole for air admission andonly needs the micropores of the material of the air inlet wall 22itself for air admission. When the atmospheric pressure inside thee-liquid storage cavity b is smaller than the atmospheric pressureoutside the atomization assembly, the air outside the atomizationassembly passes through the air inlet channel and enters the e-liquidstorage cavity b from the air inlet wall 22, so that the atmosphericpressure inside the e-liquid storage cavity b is equal to or tends to beequal to the atmospheric pressure outside the atomization assembly.

It is understandable that the speed of the air to flow into the e-liquidstorage cavity b is determined by the size of the micropore of thematerial of the air inlet wall 22 itself and the difference inatmospheric pressure between inside of the e-liquid storage cavity b andoutside of the atomization assembly. The blocking seat 14 is configuredfor guiding an airflow entering from the air inlet 132 onto the e-liquidatomization surface 21. Arrows shown in FIG. 2 indicate the flowdirection of air during the operation of the atomization assembly.

The porous body 2 may be a porous ceramic body or a fibrous body, etc.,and no concrete limitation is made here. In the present embodiment, theporous body 2 includes a first recess 23, a second recess 24 and ablocking wall 25 located between the first recess 23 and the secondrecess 24; the first recess 23 corresponds to the first perforation 121in position, and the second recess 24 corresponds to the thirdperforation 123 in position. Both of the first recess 23 and the secondrecess 24 are communicated with the e-liquid storage cavity b; an innerwall surface of the first recess 23 and an inner wall surface of thesecond recess 24 form an e-liquid contact surface p1, and the porousbody 2 adsorbs the e-liquid in the e-liquid storage cavity b by means ofthe e-liquid contact surface p1.

It is understandable that the e-liquid contact surface p1 refers to asurface of the porous body 2 which is configured for absorbing thee-liquid in the e-liquid storage cavity b by contacting the e-liquidflowing downward from the e-liquid storage cavity b; the e-liquid in thee-liquid storage cavity b enters the porous body 2 through this surface;the e-liquid contact surface p1 may be constructed by a plane or acurved surface, and there may be one or more planes or curved surfaces.

A bottom wall of the first recess 23 forms the e-liquid guide wall 21 ofwhich a bottom surface forms the e-liquid atomization surface P2, andthe porous body 3 provides, through the e-liquid atomization surface P2,the absorbed e-liquid to the heating element 3 to atomize. A bottom wallof the second recess 24 forms an air inlet wall 22 of which a bottomsurface forms the air inlet surface p3, and the air inlet surface p3 isused for allowing air to flow into the porous body 2 and flow into thee-liquid storage cavity b by means of the porous body 2; the distancebetween the air inlet surface p3 and the e-liquid contact surface p1 issmaller than the distance between the e-liquid atomization surface p2and the e-liquid contact surface p1, which means the air inlet wall 22has a smaller thickness than the e-liquid guide wall 21; therefore,external air may flow into the e-liquid storage cavity b relativelysmoothly.

Specifically, a surface of the porous body 2 away from the e-liquidstorage cavity b is a bottom surface p4 for the heating element 3 toattach onto, both of the e-liquid atomization surface p2 and the airinlet surface p3 are located within the bottom surface p4, and thebottom surface p4 is a plane, that is to say, the e-liquid atomizationsurface p2 and the air inlet surface p3 are located within one sameplane, which facilitates manufacturing. It is understandable that theheating element 3 may be completely located within the e-liquidatomization surface p2, also may be extended onto the air inlet surfacep3, and no concrete limitation is made here. The blocking wall 25includes an air hole 26 which is communicated with the aerosol channela, the e-liquid guide wall 21 and the air inlet wall 22 are located attwo opposite sides of the position of the air hole 26 respectively,making the overall ventilation relatively smoother. Since the bottomwall of the first recess 23 forms the e-liquid guide wall 21, a sidewall of the first recess 23 can also provide e-liquid for the e-liquidguide wall 21, thereby better ensuring sufficient supply of e-liquid.

Between the bottom wall of the air groove 141 and the porous body 2 isformed an atomization channel c which is configured for allowing anaerosol formed by atomization of e-liquid to flow through; theatomization channel c is communicated with the air inlet 132, the airhole 26 and the aerosol channel a, so as to discharge the aerosol formedby atomization of e-liquid to the outside of the atomization assembly.Both of the e-liquid atomization surface p2 and the air inlet surface p3are located inside the atomization channel c, which not only facilitatesthe discharge of aerosol to the outside of the atomization assembly, butalso minimizes, during the process of smoking, the difference inatmospheric pressure between insides of the e-liquid storage cavity band the atomization channel c, so that the e-liquid may easily flow ontothe e-liquid atomization surface p2. During smoking, external air flowsinto the atomization channel c from the air inlet 132, and then,together with the aerosol inside the atomization channel c, passesthrough the air hole 26 and the aerosol channel a to be discharged tothe outside of the atomization assembly.

At least part of the heating element 3 is in contact with the e-liquidguide wall 21 so as to atomize the e-liquid on the e-liquid guide wall21, which means the heating element 3 may be embedded into the e-liquidguide wall 21 and partially extended onto the e-liquid atomizationsurface p2, or the heating element 3 is an electric heating circuitprinted onto the e-liquid atomization surface p2, or one end of theheating element 3 is located on the e-liquid atomization surface p2 andthe other end is located on the air inlet surface p3. Therefore, theheating element 3 is completely or at least in part in contact with thee-liquid guide wall 21, and no concrete limitation is made here.

In the present embodiment, the heating element 3 includes a heatingsection 31, an extending section 32, a first electrical connectionportion 33 and a second electrical connection portion 34; the heatingsection 31 is attached onto the e-liquid guide wall 21 and is connectedto the first electrical connection portion 33; the heating section 31 islocated within the e-liquid atomization surface p2, which means theheating section 31 is arranged extending on the e-liquid atomizationsurface p2, thereby being able to fully atomize the e-liquid on thee-liquid atomization surface p2. A first end of the extending section 32is connected to a first end of the heating section 31, the firstelectrical connection portion 33 is connected to a second end of theheating section 31, and a second end of the extending section 32 isconnected to the second electrical connection portion 34; the extendingsection 32 has a greater cross-sectional area than the heating section31. The extending section 32 is arranged deviating from the e-liquidatomization surface p2 and is attached onto the porous body 2, therebybeing able to avoid, during operation, dry burning occurring at an areaof the porous body 2 where the extending section 32 is located.

Preferably, at least part of the extending section 32 is attached ontothe air inlet surface p3, and a contact area between the extendingsection 32 and the porous body 2 is greater than a contact area betweenthe heating section 31 and the porous body 2, thereby being able toreduce the likelihood of the e-liquid dropping from the extendingsection 32. It is understandable that the heating element 3 may be ametal wire, also may be an electric heating circuit printed onto theporous body 2, and no concrete limitation is made here, as long as itcan be electrified to generate heat. In addition, in some embodiments,the heating element 3 is completely located on the e-liquid atomizationsurface p2, and the porous body 2 may not be provided with the firstrecess 23. Of course, the porous body 2 may not be provided with thesecond recess 24 either, as long as the distance between the air inletsurface p3 and the e-liquid contact surface p1 is smaller than thedistance between the e-liquid atomization surface p2 and the e-liquidcontact surface p1.

The electrode 4 is fixed on the fixing seat 13; one end of the electrode4 presses against the heating element 3, and the other end of theelectrode 4 is electrically connected to the battery assembly. In thepresent embodiment, there are two electrodes 4; one electrode pressesagainst the first electrical connection portion 33 and the otherelectrode presses against the second electrical connection portion 24.The magnetic element 5 is fixed on the fixing seat 13 for magneticconnection with the battery assembly, so that the connection is moresecure.

The present disclosure further provides an electronic cigarette,including an atomization assembly and a battery assembly configured forsupplying power to the atomization assembly, wherein the atomizationassembly is the one described above, having the same technical effect.The battery assembly is of an available technology, and no concretelimitation is made for the structure here.

Due to the fact that the porous body 2 includes the e-liquid atomizationsurface p2 and the air inlet surface p3 that are separately arranged,the distance between the air inlet surface p3 and the e-liquid contactsurface p1 is smaller than the distance between the e-liquid atomizationsurface p2 and the e-liquid contact surface p1, and air can flow intothe e-liquid storage cavity b through the air inlet surface p3, thus,the atmospheric pressure inside the e-liquid storage cavity b is equalto or not so different from the atmospheric pressure outside theatomization assembly, the e-liquid inside the e-liquid storage cavity bcan smoothly flow onto the e-liquid guide wall 21, with sufficientsupply of e-liquid. When the heating element 3 generates heat, thee-liquid guide wall 21 can provide sufficient e-liquid, and thereforeburnt smell can be avoided.

With reference to FIG. 5 , the present embodiment is similar toEmbodiment 1 in structure, with the main difference lying in that theblocking seat 14 includes a second e-liquid holding tank 143, of which atank opening is arranged facing the porous body 2. Specifically, thetank opening of the second e-liquid holding tank 143 is arranged facingthe air inlet wall 22, to better collect the e-liquid dropping orleaking from the air inlet wall 22.

With reference to FIG. 6 , the present embodiment is similar toEmbodiment 1 in structure, with the main difference lying in that theblocking seat 14 includes a second e-liquid holding tank 143, of which atank opening is arranged facing the porous body 2. Specifically, thetank opening of the second e-liquid holding tank 143 is arranged facingthe entire bottom surface of the porous body 2, to better collect thee-liquid dropping or leaking from the porous body 2.
